Aright i'm going to move the lamp back, that's how I originally had it but I saw on here to move it to the center so the ambient temp on the cool side doesn't drop too low and so that the humidity would rise with it being over the water. I'm worried if I put the lamp over the UTH, that side will rocket into the high 90's again. The UTH is still reading like 92 with the dimmer almost off and a pseudo tile barrier between it and the tank bottom.

But i'm going to go move it like you said and see what that does. And yes I still plan on ordering a thermostat as soon as I can afford it again (recent hit to my bank account) I was just hoping the dimmer would hold me off until then
